Filter for dog hair?
My furnace has a cold air return at the end of a hall. With 2 dogs it is always sucking in tons of dog hair. My furnace man says not to put a filter behind the vent because the furnace has a much better filter and we don't want to block the air intake. The problem with the furnace filter is it costs $75 to replace (plus the service fee). Does anyone know of a way to catch the dog hair before it gets sucked into the vent so we don't have to replace the expensive filter so often?
